Abstract

The figures depict a modular construction kit for the tibial part of a knee joint prosthesis which consists of a tibial plateau (1) having pegs (2), a trunk (3) projecting into the tibia and a joint support (4) of polyethylene. Trunks (3) of different sizes can be inserted in the tibial plateau (1), and joint supports (4) of different heights are guided on all sides in a plane of the tibial plateau and can be inserted in this plane by a pivoting movement. This is done by projections (7) of the joint supports (4) engaging in a tangentially arranged pivot axis (5) in recesses of the tibial plateau and by a snap-in connection (9) engaging between the joint support (4) and the tibial plateau (1) in the opposite direction to the pivot axis. <IMAGE>

Description

  • Die Erfindung betrifft einen modularen Bausatz für den Tibiateil einer Kniegelenkprothese bestehend aus einem Tibiaplateau mit Zapfen aus einem in die Tibia hineinragenden Stamm und aus einer Gelenkauflage aus Polyäthylen. The invention relates to a modular construction kit for the tibia part of a knee joint prosthesis comprising a tibial plate with pins of a projecting into the tibia stem and of a joint support made of polyethylene.
  • In der CH-PS 667 383 ist der Tibiateil einer Kniegelenkprothese beschrieben, die aus einem Tibiaplateau mit Zapfen und aus einer Gelenkauflage besteht. In the CH-PS 667 383 of the tibial component of a knee joint prosthesis is described, which consists of a tibial plateau with cones and of a joint support. Der Einbau dieser Implantate verlangt mehrere individuelle Vorbearbeitungen bei der Resektion des Tibiaknochens, die vom mechanischen Geschick des Operateurs abhängen, um das Implantat auf der ganzen vorgesehenen Fläche abzustützen. The installation of these implants require more individual pre-processing in the resection of the tibia bone, which depend on the mechanical skill of the surgeon to support the implant around the intended area.
  • Aufgabe der Erfindung ist es, dem Operateur, der entsprechend dem vorgefundenen Knochenzustand eine einfache Resektion vorgenommen hat, ein Implantat zur Verfügung zu stellen, dessen Befestigungs- und Einbaulänge intraoperativ einstellbar sind. The object of the invention is to provide the surgeon who carried out according to the encountered bone condition, a simple resection of an implant available whose mounting and installation length are adjusted intraoperatively. Diese Aufgabe wird mit der Erfindung dadurch gelöst, dass in das Tibiaplateau unterschiedlich grosse Stämme einsetzbar sind und dass unterschiedlich hohe Gelenkauflagen in einer Ebene des Tibiaplateaus allseitig geführt durch eine Schwenkbewegung in diese Ebene einbringbar sind, indem Vorsprünge der Gelenkauflagen in einer tangential angeordneten Schwenkachse in Aussparungen des Tibiaplateaus eingreifen und indem entgegengesetzt zur Schwenkachse eine Schnappverbindung zwischen Gelenkauflage und Tibiaplateau einrastet. This object is achieved with the invention in that in the tibial plateau of different sizes strains can be used and that different levels of joint conditions in a plane of the tibia plateau on all sides guided by a pivoting motion in this plane can be introduced by projections of the joint runs in a tangentially arranged pivot axis in recesses engage the tibial plateau and engages by opposite to the pivot axis of a snap connection between the pivot bearing and the tibial plateau.
  • Der Vorteil der Erfindung besteht darin, dass mit einem ebenen, in der richtigen Winkellage zur Tibia durchgeführten Resektionsschnitt und mit der Festlegung des Bohrbildes in der Resektionsfläche alle weiteren Funktionsmasse durch Zusammenfügen von vorgefertigten Bauteilen gebildet werden. The advantage of the invention is that any further function mass are formed by joining of prefabricated components with a flat, carried out in the correct angular position for the tibial resection cut, and with the definition of the drilling pattern in the resection surface. Die abhängigen Ansprüche 2 und 3 beziehen sich auf vorteilhafte Weiterbildungen der Erfindung. The dependent claims 2 and 3 relate to advantageous further developments of the invention.
  • Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels im Zusammenhang mit der Zeichnung näher erläutert. In the following the invention with reference to an embodiment in conjunction with the drawing will be further explained. Es zeigen: Show it:

  • In den Figuren ist ein modularer Bausatz für den Tibiateil einer Kniegelenkprothese gezeigt, der aus einem Tibiaplateau mit Zapfen, aus einem in die Tibia hineinragenden Stamm und aus einer Gelenkauflage aus Polyäthylen besteht. In the figures, a modular construction kit for the tibia part of a knee joint prosthesis is shown, which consists of a tibial plateau with cone, of a projecting into the tibia stem and of a joint support made of polyethylene.
  • In das Tibiaplateau sind unterschiedlich grosse Stämme einsetzbar und unterschiedlich hohe Gelenkauflagen sind in einer Ebene des Tibiaplateaus allseitig geführt und durch eine Schwenkbewegung in diese Ebene einbringbar. In the tibial plateau large strains used are different and different levels of joint pads are guided on all sides in a plane of the tibial plateau and introduced by a pivoting movement in that plane. Dies geschieht, indem Vorsprünge der Gelenkauflagen in einer tangential angeordneten Schwenkachse in Aussparungen des Tibiaplateaus eingreifen und indem entgegengesetzt zur Schwenkachse eine Schnappverbindung zwischen Gelenkauflage und Tibiaplateau einrastet. This is done by engaging projections of the joint runs in a tangentially arranged pivot axis in recesses of the tibial plateau and snaps into place by opposite to the pivot axis of a snap connection between the pivot bearing and the tibial plateau.
  • Ein Tibiaplateau 1 besitzt ein festes Bohrbild für zwei Zapfen 2 und einen dazwischen liegenden Stamm 3, welches auf die ebene Resektionsfläche 13 eines Tibiaknochens 14 übertragen wird. A tibial tray 1 has a fixed hole pattern for two pins 2 and an intermediate stem 3, which is transmitted to the planar resected tibial bone 13 of a fourteenth Die Bohrungen für die Zapfen 2 und die Zapfendimensionen bleiben unverändert, da die Zapfen hauptsächlich der Verdrehsicherung in der Resektionsebene dienen, während der auswechselbare Stamm 3 und seine zugehörige Bohrung in ihrer Grösse stufenweise den Befestigungsmöglichkeiten im Tibiaknochen anpassbar sind, um das Tibiaplateau zu verankern. The holes for the pins 2 and the pin dimensions remain unchanged, since the pins are used mainly to rotation in the plane of resection, while the interchangeable stem 3 and its associated bore are gradually be adapted to the mounting options in the tibia bone in their size, for anchoring the tibial plateau. Die unterschiedlichen Zapfen 3 sind mit einer Verschraubung 11 im Tibiaplateau 1 befestigt. The different pin 3 are fixed with a screw 11 in the tibial plateau. 1
  • Die Gelenkauflagen 4 liegen in unterschiedliche Höhen gestuft vor, während die Anschlussmasse zu einem Tibiaplateau 1 für alle Höhen gleich sind. The joint support means 4 are situated in different heights before stepped, while the port dimensions should be a tibial tray 1 for all heights equal. Die Gelenkauflagen 4 liegen in einer Ebene 6, die durch den hochgezogenen Begrenzungsrand 15 des Tibiaplateaus gebildet wird, auf und sind in dieser Ebene durch Führungselemente 10 mit ihrem vorstehenden Innenteil 16 geführt, das der Kontur des hochstehenden Begrenzungsrandes 15 nachgeformt ist. The hinge supports 4 lie in a plane 6, which is formed by the raised boundary edge 15 of the tibial plateau, and are guided in this plane by means of guide elements 10 with its projecting inner portion 16, which is reshaped to the contour of the upstanding bounding edge 15 °. Posterior weist der Begrenzungsrand 15 auf seiner Innenseite zwei Aussparungen 8 auf, die auf einer gemeinsamen Tangente an den Innenteil 16 liegen, während der Innenteil 16 der Vorsprünge 7 besitzt, die durch eine Schwenkbewegung in die Aussparungen 8 einhängbar sind. Posterior, the boundary edge 15 on its inside two recesses 8 which lie on a common tangent to the inner part 16, while the inner part 16 has the protrusions 7, which are suspended by a pivoting movement into the recesses. 8 Die Vorsprünge 7 und die Aussparungen 8 bilden eine Schwenkachse 5, an der durch Einschwenken der Gelenkauflage 4 eine einseitige Sicherung gegen Herausfallen aus der Ebene 6 entsteht. The protrusions 7 and the recesses 8 define a pivot axis 5, by pivoting the pivot support 4 a one-sided securing against falling out of the plane 6 is formed at the. Auf der Gegenseite zur Schwenkbachse 5 ist eine Schappverbindung 9 zwischen Begrenzungsrand 15 und Innenteil 16 angebracht, die mit dem Aufliegen der Gelenkauflage 4 auf der Ebene 6 einrastet. On the opposite side to the Schwenkbachse 5 is a Schappverbindung 9 is mounted between the boundary edge 15 and inner part 16, which engages with the contact of the joint overlay 4 on the plane. 6 In Fig. 3 ist über der Schnappverbindung 9 zwischen Begrenzungsrand 15 und Gelenkauflage 4 eine Ausnehmung 12 gezeigt, in die ein schraubenzieherähnliches Werkzeug als Hebel einsetzbar ist, um die Verhakung in der Schnappverbindung 9 zu lösen. In Fig. 3 is connected via the snap connection 9 shown a recess 12 between boundary edge 15 and pivot support 4, into which a screwdriver-like tool is used as a lever to 9 to release the hooking in of the snap connection. Die Gelenkauflage 4 ist unabhängig von der Schnappverbindung senkrecht zur Schwenkachse 5 in der Ebene 6 durch den Begrenzungsrand 15 geführt, damit keine Verschiebekräfte in der Ebene 6 auf die Schnappverbindung 9 wirken können, dh die Schnappverbindung 9 sichert senkrecht zur Ebene 6 und wird nicht durch wechselnde Zentrierkräfte ermüdet. The joint support 4 is performed independently of the snap connection perpendicular to the pivot axis 5 in the plane 6 through the boundary edge 15, so that no displacement forces can act on the snap-on connection 9 in the plane 6, that the snap connection 9 secures perpendicular to the plane 6 and is not changing centering forces fatigued. Im montierten Zustand sind der Innenteil 16 und der Grund des Tibiaplateaus 1 weniger als 1/10 mm voneinander entfernt, damit im Rahmen der Elastizität der beiden Teile weitere tragende Flächen bei Belastung entstehen. In the assembled state of the inner part 16 and the base of the tibial plateau 1 are less than 1/10 mm away from each other so that there are under the elasticity of the two parts more bearing surfaces under load.
